My problem with paralysis isn't anything about the spell itself (I think it's fine, though I wouldn't object strongly agains a
slight duration reduction.) What does bother me is that the AI, once scripting runs out insist on spamming it over and over in preference over soul slay, even with high level astral mages.
While I could possibly understand S3 caster to default to paralyze for fatigue reasons, in my opinion anything S4 or higher should always go for soul slay, to prevent the all too common 50-turn-desperate-but-doomed-attempts-to-kill-the-opposing-SC-followed-by-the-inevitable-turn-limit-rout. This should go double for any mages in a communion, who shouldn't care too much about fatigue. (As opposed to the player setting up the communion, who should defintely worry about setting it up so the masters don't have to worry.
